Amazon MP3 has always had a few advantages over iTunes, like higher bitrate tracks and great integration with DoubleTwist for non-Apple devices. This weekend, they pushed the envelope even more, lowering their prices to hard-to-ignore levels. While iTunes jacked up the prices to popular songs from $0.99 to $1.29, Amazon is now selling many of those same tracks for a measly $0.69. They've always been a bit ahead of iTunes on the price game (they were only $0.89 before), but a fairly extensive catalog of $0.69 tracks is pretty hard to turn down. If you've foregone Amazon's MP3 store in the past, it might be time for another look—at least if you're into popular music. [Los Angeles Times via TUAW]
